Abstract (en)
[origin: WO2009047316A1] The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing two linked iodinated phenyl groups of the general formula (I) and salts or optical active isomers thereof, wherein each of R1, R2 and R3 independently are the same or different and denote a hydrogen atom or a C1 to C4 straight of branched alkyl group; each R4 independently are the same or different and denote C1 to C6 straight of branched alkyl moieties substituted by up to 6 -OH groups; and each R5 independently are the same or different and denote C1 to C6 straight of branched alkyl moieties substituted by up to 6 -OH groups provided that at least one alkyl group is substituted with at least 2 hydroxy groups. The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging, and to contrast media containing such compounds.
